SPECIFIGATIGN' forming part of .Letters Patent No. 722,819, dated March17, 1903. Application filed July 1, 1902 Serial No. 113,965- (No model.)

To all whom, it may concern:

Be it known that LWILLIAM MORE DECKER, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new anduseful.

Improvements in Syringes; and I do hereby declare the following to be afull, clear, and exact'description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain new and useful improvements in syringes,and particularly to that class commonly denominated as water-bag orfountain syringes. In this particular class of syringes the bag isprovided with an opening at the upper end, through which the bag isfilled, and with a suitable stopper or screw-cap for closing saidopening and at the lower extremity with a tip adapted to receive asection of hose or rubber tubing, to which may be secured the usual andvarious nozzles. This class of syringes cannot be made to operatesuccessfully unless it is held by an assistant or suspended from somesuitable support, and its action is at all times dependent upon theforce of gravity, and consequently upon the height at which the bag isheld or suspended. In hospital use a hook or support is not alwaysconvenient, in which case the nurse who may be administering a douche iscompelled -to hold the syringe in an elevated position, and hence theassistance which the nurse ought to give to a patient is necessarilyrestricted, and in all cases it becomes necessary to have acomparativelylong hose or tube in order that the bag may be held sufliciently high toproduce the necessary gravity, for if the bag is held too low it willnot operate, because the fluid will be so sluggish and irregular thatthe results would not be satisfactory.

My invention has for its object to provide a syringe which shallovercome all of the disadvantages named and which may be used by eithera patient or nurse to produce a flow independent of gravity, and henceindependent of the height at which the syring may be located, and whichshall be entirely under the control of the operator.

W'ith these ends in view my invention consists of a bag-syringe ofpeculiar construction and having combined therewith a truck dicated indotted lines.

in any suitable manner.

adapted to cooperate with the bag in expelling or forcing the fluidcontents of the latter through thehose and nozzle of the syringe, aswill be hereinafter more fully described.

My invention further consists in the details of construction of thewater-bag or syringe proper and also in the details of construction ofthe truck designed to cooperate with said bag, all as will behereinafter-more fully described.

In order that those skilled in the art to which my invention appertainsmay know how to make and use the same and fully understand all of itsadvantages, I will proceed to describe my invention,referring bycharacters to the accompanying drawings, in which- Figure 1 represents aperspective view of myimproved syringe and truck arranged in operativerelation. Fig. 2 is a side or edge elevation of the same. Fig. 3 is atop or plan view of the truck with the bag or syringe proper removed.Fig. 4 is a detail perspective on enlarged scale, showing thearticulative portions of one end of the truck-frame slightly separated.Fig. 5 is a similar view of the opposite end of the truck and showingmeans for locking the two parts of the frame securely together with themangles or rollers confined therein in proper position. Fig. 6 is a topor plan view of what is shown at Fig. 5,

but in locked position, the lock being shown in dotted lines; and Fig. 7is a front or rear view of the bag on a decreased scale.

Similar characters of reference denote like parts in the several figuresof the drawings.

A is a bag, of rubber or other suitable material and preferably oblongor of rectangular form, the upper end of which is strengthened orreinforced in any manner well understood by manufacturers of rubbergoods and as inh At each corner of this reinforced upper portion of thebag are provided eyelets or gromets B, adapted to receive suitable hooksG at each end of an operating-handle D. The upper edge of the bag ismutilated or cut away, as shown at E, and is stifiened to preventcorrugation or crimping when traction ismade upon the bag by a rod F,inthecenter of which is formed an eye G. This rod F is secured withinthe edge or selvage of the upper end of the bag The open space E port,such as a hook or nail, when it may be desired to use the syringe in theordinary manner without the truck and as a fountainsyringe. The eyeletsor gromets B serve not only to receive the hooks C of the handle D whenthe syringe is operated, as indicated at Fig. 1, to draw the bag betweenthe rollers of the truck, but when it may be desirable to hold the bagstationary and draw the truck down upon the bag, as shown at Fig. 2, the

hooks H on the shoulder-strap I are passed through said eyelets orgromets. The lower end of the bag is provided with a centrallyarrangedfilling tip or nipple J, which may or may not he provided with avalve-cock K, and in the absence of the cock K the hosetube L may beprovided with any of the wellknown clamping devices for shutting off theflow of the contents of the bag A. The nipple at its lower extremity isformed with a suitable flange or enlargement J for proper connectionwith the hose L, the opposite or free end of which is adapted to receiveany suitable nozzle M, the one shown in the drawings representing animproved vaginal nozzle constituting the subject-matter of anapplication for Letters Patent filed by me July 1, 1902, Serial No.113,967.

Having described the novel features of construction of the bag orsyringe proper, I will now describe the cooperating device, which-Idenominate the truck. This truck consists of two sections N N, one endof each of such sections being formed with knuckles 0, provided withpintle-channels P, as shown at Fig. 4, to receive a suitable pintle Q,so that they may be articulatively connected, as shown at Fig. 3. Theopposite ends of the sections N are constructed as shown at Fig. 5, onewith a transverse slot R and a spring or sliding latch S and the otherwith lugs T and a longitudinal latch recess or keeper U. One of each ofthe ends of the sections N is formed with a flanged trunnion V, adaptedto receive the hooks H on the suspension-trap 'I, heretofore referredto, and both of the ends of each of the sections N is formed with alongitudinal recess W, as clearly shown at Figs. 4: and 5, to receive anadjustable journal block or box X, (see Fig. 5,) which is provided witha screw-threaded rod Y, adapted to enter the female thread of anoperatingnut Z, located within one corner of the section N and by meansof which the journal box or block may be adjusted longitudinally withinthe slot W in an obvious manner. When only one of the sections isprovided with the adjustable journal box or block X, the opposite andadjacent end of the other section has the latch-keeper U elongated orextended sufficiently to receive a stationary Fig. 2.

journal-box, and each of the four journalboxes are formed withcylindrical recesses or channels 1 (see Fig. 5) to receive the ends ofthe journals 2 of the pair ofrollers or mangles 3. These journals 2 maybe fixed in relation with the rollers 3 and rotate within thejournal-boxes X,or the rollers may be free to rotate upon the journals2. One or both of the rollers 3 may be provided with end flanges 4 (seeFig. 3) to prevent the water-bag A from moving laterally during itsprogress between the rollers, or any other suitable means may beemployed for this purpose.

From the construction shown and described it will be readily seen thatbefore the articulative sections of theframe of the truck are puttogether the journal-boxes X and rollers 3 may be properly locatedandthat when the two sections are locked together, as shown at Fig. 1,thejournal-boxes, with the rollers, are

all held in proper position and that one or both of the rollers may beadjusted by the rotation of the nuts Z, as heretofore described, tocontrol the bite or space between the rollers.

In the ordinary use of my improved syringe and truck the bag A isfilledpor loaded with the fluid douche and the latch or look S iswithdrawn from the keeper-slot U in order that the frame may be suitablyopened by articulation upon the pintle Q, so that the upper end of thebag A may be located within the bite of or between the rollers 3 3,after which the frameis closed and securely locked. The truck is thensuspended upon the shoul- ,ders of the operator, whether the operator bea nurse or a patient, by meansof the strap I, passed over the shouldersand adjusted to any desired attitude by means of any suitable adjustingdevices 5 on the strap. The nozzle M is then properly adjusted withinthe per.- son of the patient and then through the medium of the handle Dor by grasping the rod F the bag A is pulled between the bite of therollers 3 3 and the contents of the bag A is forced through the hose Land nozzle M with a force commensurate to the celerity with which thebag is moved between the rollers. If it be desired to expel the contentsof the bag by holding said bag stationary and moving the truck over thebag, the hooks H on the ends of the shoulder-strap Iare connected withthe rod F in the upper edge of the bag and a figure 8 or other loop 6 ispassed over the trnnnions V of the truck-frame and the hooks O of thehandle D passed into the opposite ends of said loops 6, as clearlyindicatedin In either case the syringe may be operated under any and allconditions and may be connected with any part of the body of theoperator. For instance, if the syringe is operated by the patient whomay be upon the back with the knees drawn up or flexed the strap I maybe secured about the knees, and the operator then reaching and graspingthe handle D or rod F may pull the bag with facility and said bagemptied as rapidly as desired. Likewise the patient may pass the straparound one or both of the pedal extremities, and the bag lying upon thecouch the operator taking hold of the handle D may draw the bag throughthe rollers.

From the construction and manner of using my invention as alreadydescribed it will be obvious that the hose L maybe much shorter thanwould be required with an ordinary fountain-syringe, because the syringemay be brought much closer to the patient not requiring altitude tosecure gravity force.

The bag A may be used as an ordinary hotwater bag when desired byclosing the cock K or entirely removing the nipple J and substitutingtherefor an ordinary cork.

For lightness and economy of construction the rollers or mangles 3 3 maybe made hollow, and the truck is composed of light castings, which maybe nickel-plated or rendered attractive in appearance in any othermanner.

Vhile I have shown the truck of rectangular form, it will be understoodthat its design may be varied without departing from the genus of myinvention so long as it is adapted to operate in the manner described toexpel the contents of the bag, and it will also be understood that I donot wish to be limited to the particular design shown of the water-bag.

.As I have already stated, the results sought to be obtained by myimprovements may be secured whether the bag be drawn through the bite ofthe rollers of the truck while the latter is held stationary or the bagmay be held stationary and the truck drawn over the same, and the flowof the contents of the bag are not only delivered with any desiredforce, but may be entirely suspended by a cessation of the relativemovements of the bag or truck.

The rod F in the upper edge of the bag not only prevents the corrugationor crimping while under traction, as hereinbet'ore explained, butprevents this result at all other times.

Having described the construction and operation of m yimproved syringeand truck and its many advantages, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a syringe, the combination with a fluid-containing bag, providedwith a handle at one end and a hose connection at the opposite end, atruck-frame adapted to open to receive the bag, and provided withrollers, ad-

j ustable relative to one another, and adapted to travel over the bag toforce the contents thereof through the nozzle, substantially ashereinbefore set forth.

2. A water-bag syringe closed at its upper end to form adouble-thickness margin from edge to edge, adapted to pass betweencompressing-rollers, and provided at each corner with an eyelet orgromet, and provided at its lower end with an induction and eductionconduit adapted for connection with a nozzlehose, substantially ashereinbefore set forth.

3. A water-bag closed at its top and provided with a hose connection atits bottom, the top cut away centrally and bridged with a metal rodsecured to the top each side of the opening, whereby the rod maysubserve the purpose of ahandle,.substantially as hereinbefore setforth.

In testimony whereof I affix my signature in presence of two witnesses.
